73138828 ÷ 579 
The aim is to understand the frequency of 579 in 73138828.

Moving on to step 1:
579 can be fit into 7 0 times, resulting in a remainder of 7.
The next digit of our result is 0. 
Result so far: 0.0
Deduct 0 from 7 and we're left with 7.
Take the next digit (3) from the dividend and append it to 7, then repeat: 73 / 579

Advancing to step 2:
The number 579 fits into 73 0 times, leaving a remainder of 73.
Put 0 as the next digit of the answer. 
Result so far: 0.0
Subtracting 0 from 73 leaves us with 73.
Bring next digit (1) of the dividend behind the 73 and repeat the process: 731 / 579

Let's proceed to step 3:
If we divide 731 by 579, we get 1 and a remainder of 152.
Use 1 as the next digit of our solution. 
Result so far: 1.0
Subtracting 579 from 731 leaves us with 152.
Take the next digit (3) from the dividend and append it to 152, then repeat: 1523 / 579

Step 4:
When dividing 1523 by 579, we get 2 with a remainder of 365.
Record the quotient 2 as the next digit in the result. 
Result so far: 12.0
Deduct 1158 from 1523 and we're left with 365.
Take the next digit (8) from the dividend and append it to 365, then repeat: 3658 / 579

Going ahead to step 5:
579 goes into 3658 6 times with a remainder of 184.
The number 6 becomes the next digit in our result. 
Result so far: 126.0
Deduct 3474 from 3658 and we're left with 184.
Append the next digit (8) from the dividend to 184 and continue with: 1848 / 579

Advancing to step 6:
579 goes into 1848 3 times with a remainder of 111.
Use 3 as the next digit of our solution. 
Result so far: 1263.0
If we take 1737 away from 1848, we end up with 111.
Take the next digit (2) from the dividend and append it to 111, then repeat: 1112 / 579

Moving on to step 7:
When dividing 1112 by 579, we get 1 with a remainder of 533.
Record the quotient 1 as the next digit in the result. 
Result so far: 12631.0
The remainder is 533 after subtracting 579 from 1112.
Take the next digit (8) from the dividend and append it to 533, then repeat: 5338 / 579

Moving on to step 8:
5338 divided by 579 is 9 with a remainder of 127.
Write down 9 as next digit of the result. 
Result so far: 126319.0
If we take 5211 away from 5338, we end up with 127.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1270, and continue the process.

Step 9:
579 can be fit into 1270 2 times, resulting in a remainder of 112.
Record the quotient 2 as the next digit in the result. 
Result so far: 126319.2
If we subtract 1158 from 1270, we get 112.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1120, and continue the process.

Moving on to step 10:
If we divide 1120 by 579, we get 1 and a remainder of 541.
The next digit of our result is 1. 
Result so far: 126319.21
Deduct 579 from 1120 and we're left with 541.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5410, and continue the process.

Step 11:
When dividing 5410 by 579, we get 9 with a remainder of 199.
The number 9 becomes the next digit in our result. 
Result so far: 126319.219
If we subtract 5211 from 5410, we get 199.
Since there are no more digits in the dividend, we add a zero to the remainder making it 1990, and continue the process.

Let's proceed to step 12:
579 can be fit into 1990 3 times, resulting in a remainder of 253.
Write down 3 as next digit of the result. 
Result so far: 126319.2193
The remainder is 253 after subtracting 1737 from 1990.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2530, and continue the process.

Let's proceed to step 13:
579 goes into 2530 4 times with a remainder of 214.
Use 4 as the next digit of our solution. 
Result so far: 126319.21934
Subtract 2316 from 2530 to get 214.
Since there are no more digits in the dividend, we add a zero to the remainder making it 2140, and continue the process.

Let's proceed to step 14:
2140 divided by 579 is 3 with a remainder of 403.
Put 3 as the next digit of the answer. 
Result so far: 126319.219343
The remainder is 403 after subtracting 1737 from 2140.
Since there are no more digits in the dividend, we add a zero to the remainder making it 4030, and continue the process.

Moving on to step 15:
579 can be fit into 4030 6 times, resulting in a remainder of 556.
The number 6 becomes the next digit in our result. 
Result so far: 126319.2193436
Subtract 3474 from 4030 to get 556.
Since there are no more digits in the dividend, we add a zero to the remainder making it 5560, and continue the process.

Moving on to step 16:
579 can be fit into 5560 9 times, resulting in a remainder of 349.
The next digit of our result is 9. 
Result so far: 126319.21934369
The remainder is 349 after subtracting 5211 from 5560.
Since there are no more digits in the dividend, we add a zero to the remainder making it 3490, and continue the process.

The final outcome is 126319.21934369, with a leftover of 3.49e-07.
